Answer:
[tex]\huge\boxed{2329 \ \text{pounds}}[/tex]
Step-by-step explanation:
In order to solve this equation, let's see what we already know.
We know two points on the graph which we can use to find the slopeThat's about it.
However, this can come useful to find the slope between the two points, which is the slope for the entire graph (since this is linear). The slope between two points is usually defined as [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Our two points are (18, 2017) and (48, 2212).
The change in y between our two points is [tex]2212-2017 = 195[/tex], and the change in x is [tex]48 - 18 = 30[/tex]. Our slope will then be [tex]\frac{195}{30}[/tex], which comes out to be approximately 6.5. Therefore, our slope is 6.5.
Now that we know the slope, we can substitute inside our equation in slope intercept form.
[tex]y = 6.5x+b[/tex]
We have yet to find b, the y-intercept (how much the plane itself weighs). To find b, we can substitute a point on the graph into the equation and solve for b. We know that the point (18, 2017) is on the graph so let's use that.
[tex]2017 = 6.5 \cdot18 + b[/tex] [tex]2017 = 117 + b[/tex] [tex]1900= b[/tex]Now that we know our y-intercept is 1900, we can create our equation by using the slope and the y-intercept.
[tex]y=6.5x+1900[/tex]
Finally, to find the weight of the plane with 66 pounds of fuel, we can substitute 66 inside this equation as x.
[tex]y = 6.5 \cdot66+ 1900[/tex] [tex]y = 429+1900[/tex] [tex]y=2329[/tex]So the plane weighed 2329 pounds with 66 gallons of fuel.
Hope this helped!

Shelia buys flower bulbs from a catalog $2 each and $4 shipping charge for the whole order. She spends $20 on flower bulbs. The model can be used to describe x, the number of bulbs Shelia can order. Write an equation to determine the number of bulbs Shelia can order. How many bulbs did she order?
Answer:
8 bulbs
Step-by-step explanation:
Step one:
Given data
Shelia buys flower bulbs from a catalog for $2 each and $4 shipping charge for the whole order
we are told that the total money spent is $20
let the number of bulbs ordered be x, and the total money spent be y
the equation for the situation is
y=2x+4
for a total amount of $20, we want to find x
20=2x+4
20-4=2x
16=2x
divide both sides by 2
x= 16/2
x= 8 bulbs
5. Lines s and t intersect as shown in the picture. Which pair of angles are vertical?
A. angle 7 and angle 10
B. angle 9 and angle 10
C. angle 8 and angle 10
D. angle 7 and angle
Answer: angle 7 and angle 10
Step-by-step explanation: trust me its correct
Answer:
The right answer is 9 and 10. It is not 7 and 10 because if you can see one of the arrows for 10 is shorter than the arrow next to it for angle 7.
9 and 10 have one straight line that it is on than both share the short arrow.
The straight line 2x + 3y = 7 meets the curve
xy + 10 = 0 at the points P and Q. Calculate the
gradient of the curve at P and at Q.
Step-by-step explanation:
xy + 10 = 0. => y = -10/x.
2x + 3y = 7. => 3y = -2x + 7, y = -2/3 x + 7/3.
When -10/x = -2/3 x + 7/3,
-10 = -2/3 x² + 7/3 x, 2/3 x² - 7/3 x - 10 = 0.
=> 2x² - 7x - 30 = 0
=> (2x + 5)(x - 6) = 0
=> x = -2.5 or x = 6.
dy/dx = d/dx [-10/x] = 10/x².
When x = -2.5, dy/dx = 10 / (-2.5)² = 1.6.
When x = 6, dy/dx = 10 / (6)² = 5/18.
Hence the gradients at the points are 1.6 and 5/18.

3x + 2 6x - 20
Step-by-step explanation:
Remember that the sum of angles on a straight line are supplementary. (180°)
Therefore 3x + 2 + 6x - 20 = 180.
=> 9x - 18 = 180
=> 9x = 198
=> x = 22.

Answer:
[tex]x = \frac{367}{3}[/tex]
[tex]y = \frac{173}{3}[/tex]
Step-by-step explanation:
Equations
Let's call
x = measure of angle 1
y = measure of angle 2
The angles are supplementary, thus their sum is 180°:
x + y = 180 [1]
It's also known that one angle (x) is 7° more than twice the other (y), thus:
x = 7+ 2y [2]
Substituting [2} in [1]:
7+ 2y + y = 180
Operating:
7+ 3y = 180
Subtracting 7:
3y = 180 - 7 = 173
Dividing by 3:
[tex]y = \frac{173}{3}[/tex]
And:
[tex]x = 7+ 2*\frac{173}{3}[/tex]
[tex]x = \frac{367}{3}[/tex]

if the median of data Carranged
in acending order 31, 33, 35,Xxx Mo,
48, 48, 50 is 40 then find value of
X
Answer:
35
Step-by-step explanation:
If the median of data (arranged in ascending order) 31,33,35,x,x+10,48,48,50 is 40,then find value of x.
Solution:
The median of a data is the middle number after the numbers from the data have been arranged either from least to greatest or from greatest to least. For an even number of data, the median is the average of the middle two numbers.
The data arranged in ascending order is:
31,33,35,x,x+10,48,48,50
SInce the data has an even number (8), the median is the average of the middle two numbers.
Median = average of x and x + 10
[x + (x + 10)] / 2 = median
[x + (x + 10)] / 2 = 40
x + x + 10 = 80
2x + 10 = 80
2x = 70
x = 70/2
x = 35

a. It appears that Mike's grade point average for the second quarter is 3 times his first quarter
average. Change the intervals on the vertical scale so they are consistent.
b. It appears that Mike's grade point average for the second quarter was significantly larger than
his first quarter average. Change the width of the bars to display the correct scale.
c. It appears that Mike's grade point average for the second quarter is 2 times his first quarter
average. Change the intervals on the horizontal scale so they are consistent
d. There is no way to change the graph so it is not misleading
The way to change it so that it is not misleading is A. It appears that Mike's grade point average for the second quarter is 3 times his first quarter average. Change the intervals on the vertical scale so they are consistent.
How to illustrate the graph?A diagram or pictorial representation that organizes the representation of data or values is known as a graph. The relationships between two or more things are frequently represented by the points on a graph.
Mike's grade point average for the second quarter appears to be three times higher than for the first. The vertical scale's intervals should be adjusted to make them uniform. In this case, the correct option is A.

Find the values of a and b such that x^2-2x+2=(x-a)^2+b
Answer:
a = 1, b = 1
Step-by-step explanation:
Expand the right side and compare the coefficients of like terms on both sides, that is
right side
(x - a)² + b ← expand factor using FOIL
= x² - 2ax + a² + b
Compare to left side x² - 2x + 2
Compare the coefficients of the x- term
- 2a = - 2 ( divide both sides by - 2 )
a = 1
Compare the constant terms
a² + b = 2 ( substitute a = 1 )
1² + b = 2
1 + b = 2 ( subtract 1 from both sides )
b = 1
Thus a = 1, b = 1
